BACKGROUND Technical Field

This disclosure relates generally to architecture for a camera with folded optics and lens shifting capabilities.

Description of the Related Art

The advent of small, mobile multipurpose devices such as smartphones and tablet or pad devices has resulted in a need for high-resolution, small form factor cameras for integration in the devices. Some small form factor cameras may incorporate optical image stabilization (OIS) mechanisms that may sense and react to external excitation/disturbance by adjusting location of the optical lens on the X and/or Y axis in an attempt to compensate for unwanted motion of the lens. Some small form factor cameras may incorporate an autofocus (AF) mechanism whereby the object focal distance can be adjusted to focus an object plane in front of the camera at an image plane to be captured by the image sensor. In some such autofocus mechanisms, the optical lens is moved as a single rigid body along the optical axis of the camera to refocus the camera.

This specification includes references to “one embodiment” or “an embodiment.” The appearances of the phrases “in one embodiment” or “in an embodiment” do not necessarily refer to the same embodiment. Particular features, structures, or characteristics may be combined in any suitable manner consistent with this disclosure.

“Comprising.” This term is open-ended. As used in the appended claims, this term does not foreclose additional structure or steps. Consider a claim that recites: “An apparatus comprising one or more processor units . . . .” Such a claim does not foreclose the apparatus from including additional components (e.g., a network interface unit, graphics circuitry, etc.).

“Configured To.” Various units, circuits, or other components may be described or claimed as “configured to” perform a task or tasks. In such contexts, “configured to” is used to connote structure by indicating that the units/circuits/components include structure (e.g., circuitry) that performs those task or tasks during operation. As such, the unit/circuit/component can be said to be configured to perform the task even when the specified unit/circuit/component is not currently operational (e.g., is not on). The units/circuits/components used with the “configured to” language include hardware—for example, circuits, memory storing program instructions executable to implement the operation, etc. Reciting that a unit/circuit/component is “configured to” perform one or more tasks is expressly intended not to invoke 35 U.S.C. § 112, sixth paragraph, for that unit/circuit/component. Additionally, “configured to” can include generic structure (e.g., generic circuitry) that is manipulated by software and/or firmware (e.g., an FPGA or a general-purpose processor executing software) to operate in manner that is capable of performing the task(s) at issue. “Configure to” may also include adapting a manufacturing process (e.g., a semiconductor fabrication facility) to fabricate devices (e.g., integrated circuits) that are adapted to implement or perform one or more tasks.

“First,” “Second,” etc. As used herein, these terms are used as labels for nouns that they precede, and do not imply any type of ordering (e.g., spatial, temporal, logical, etc.). For example, a buffer circuit may be described herein as performing write operations for “first” and “second” values. The terms “first” and “second” do not necessarily imply that the first value must be written before the second value.

“Based On.” As used herein, this term is used to describe one or more factors that affect a determination. This term does not foreclose additional factors that may affect a determination. That is, a determination may be solely based on those factors or based, at least in part, on those factors. Consider the phrase “determine A based on B.” While in this case, B is a factor that affects the determination of A, such a phrase does not foreclose the determination of A from also being based on C. In other instances, A may be determined based solely on B.

It will also be understood that, although the terms first, second, etc. may be used herein to describe various elements, these elements should not be limited by these terms. These terms are only used to distinguish one element from another. For example, a first contact could be termed a second contact, and, similarly, a second contact could be termed a first contact, without departing from the intended scope. The first contact and the second contact are both contacts, but they are not the same contact.

The terminology used in the description herein is for the purpose of describing particular embodiments only and is not intended to be limiting. As used in the description and the appended claims, the singular forms “a”, “an” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will also be understood that the term “and/or” as used herein refers to and encompasses any and all possible combinations of one or more of the associated listed items. It will be further understood that the terms “includes,” “including,” “comprises,” and/or “comprising,” when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof.

As used herein, the term “if” may be construed to mean “when” or “upon” or “in response to determining” or “in response to detecting,” depending on the context. Similarly, the phrase “if it is determined” or “if [a stated condition or event] is detected” may be construed to mean “upon determining” or “in response to determining” or “upon detecting [the stated condition or event]” or “in response to detecting [the stated condition or event],” depending on the context.

DETAILED DESCRIPTION

Some embodiments include camera equipment outfitted with controls, magnets, and voice coil motors to improve the effectiveness of a miniature actuation mechanism for a compact camera module. More specifically, in some embodiments, compact camera modules include actuators to deliver functions such as autofocus (AF) and/or optical image stabilization (OIS). One approach to delivering a very compact actuator for AF and/or OIS is to use a voice coil motor (VCM) actuator.

Reference will now be made in detail to embodiments, examples of which are illustrated in the accompanying drawings. In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the present disclosure. However, it will be apparent to one of ordinary skill in the art that some embodiments may be practiced without these specific details. In other instances, well-known methods, procedures, components, circuits, and networks have not been described in detail so as not to unnecessarily obscure aspects of the embodiments.

Described here are folded optics arrangements for providing a reduced-height imaging system. The arrangements discussed throughout generally comprise one or more lenses and one or more light path folding elements (e.g., a prism, a mirror, etc.), which collectively provides a folded light path. The one or more lenses may be moveable the light path folding element(s) and/or an image sensor to provide autofocus and/or image stabilization during imaging. FIG. 1 shows a generalized example of a camera 100 with a folded optics arrangement. The example X-Y-Z coordinate system shown in FIG. 1 is used to discuss aspects of systems and/or system components, and may apply to embodiments described throughout this disclosure.

In various embodiments, the camera 100 may include a lens group 102, a prism 104, and an image sensor package 106. The lens group 102 may include one or more lens elements. In some embodiments, the lens group 102 may be located between the prism 104 and the image sensor package 106. Light may follow an optical path 108 that is folded by the prism 104 such that the light is directed towards the lens group 102, passes through the lens group 102, and propagates towards the image sensor package 106. In some examples, light may enter an object side of the prism 104 along the Z-axis. The prism 104 may redirect the light to propagate along the X-axis (which may be parallel to an optical axis defined by the lens group 102) towards the lens group 102 and the image sensor package 106. The prism 104, the lens group 102, and/or the image sensor package 106 may be positioned along a common axis (e.g., the X-axis, the optical axis defined by the lens group 102, etc.). According to some examples, the optical path 108 may be contained within a plane (e.g., the X-Z plane), and the image sensor package 106 may extend along a different plane (e.g., the Y-Z plane).

In some embodiments, the object side of the prism 104 may extend along the X-Y plane. Furthermore, the prism 104 may include a pair of opposing lateral sides that each extend along the X-Z plane, a lens group facing side that extends along the Y-Z plane, and a reflecting surface side that is angled relative to one or more of the other sides of the prism 104. For example, the reflecting surface side of the prism 104 may include a reflective surface that is angled so as to redirect light received from the object side of the prism 104 towards the lens group 102 (via the lens group facing side of the prism 104) and/or the image sensor package 106, as discussed above.

While the light path folding element(s) are shown in various figures as comprising prisms (e.g., the prism 104), the camera systems and/or folded optics arrangements described herein may include any suitable light path folding element (e.g., a mirror or the like) or combination of elements. In some embodiments, one or more of the light path folding elements may also act as a lens element (or combination of lens elements). For example, one or more lens elements (e.g., other than those of the lens group 102) may be integrated with the prism 104 such that the prism acts as a lens element. Additionally, or alternatively, the prism 104 may be shaped such that the prism 104 acts as a lens element.

As will be discussed in further detail below, the lens group 102 may be coupled with an actuator structure that is configured to move the lens group 102 along multiple axes, e.g., to provide autofocus (AF) and/or optical image stabilization (OIS) functionality. FIG. 2 shows an example of 3-axis movement of the lens group 102 to provide AF and/or OIS functionality. For example, the lens group 102 may be shifted (e.g., by an actuator structure, such as the actuator structures/arrangements discussed in further detail below) along the X-axis to provide AF movement. Additionally, or alternatively, the lens group 102 may be shifted along the Z-axis to provide OIS-Z movement (e.g., movement that shifts the image projected on the image sensor package 106 in one or more directions parallel to the Z-axis). Additionally, or alternatively, the lens group 102 may be shifted along the Y-axis to provide OIS-Y movement (e.g., movement that shifts the image projected on the image sensor package 106 in one or more directions parallel to the Y-axis). Components of the camera 100 (e.g., the lens group 102, the prism 104, and/or the image sensor package 106, etc.) may be used with any of the actuator arrangements described in the following figures.

As mentioned above, the camera systems described here may comprise an actuator system to move the lens group relative to one or more light path folding elements (e.g., the prism 104). The actuator arrangements described here may generally comprise one or more carrier structures (e.g., the inner carrier structures and/or the outer carrier structures of the carrier arrangements discussed below), one or more suspension structures for moveably holding the carrier structure(s) relative to the rest of the camera and/or for moveably holding a carrier structure relative to another carrier structure, and an actuator module for controlling movement of the carrier structure(s). FIGS. 3 and 4 illustrate an exploded view and a side cross-sectional view, respectively, of an example camera 300 with a folded optics arrangement.

In some embodiments, the camera 300 may include a lens group 302, a prism 304, and an image sensor 306. The lens group 302 may include one or more lens elements disposed within a lens barrel 308.

As will be discussed in further detail below, the camera 300 may include an actuator module that provides for shifting the lens group 302 along multiple axes, e.g., to provide AF and/or OIS movement. In some embodiments, the actuator module may comprise a voice coil motor (VCM) actuator module that includes one or more VCM actuators. For instance, the actuator module may include one or more magnets and one or more coils. The magnets and coils may magnetically interact (e.g., when electrical current is provided to the coils) to produce Lorentz forces that move the lens group 302.

According to various embodiments, the camera 300 may include a carrier arrangement that includes an inner carrier structure (e.g., the lens barrel 308 and/or a lens carrier 310) and an outer carrier structure (e.g., a magnet holder 312 and/or a magnet frame). In some embodiments, the magnet holder 312 may extend at least partially around the prism and the lens barrel 308 (and the lens group 302). For instance, as shown in FIG. 3, the magnet holder 312 may be U-shaped in some embodiments.

The magnet holder 312 may have multiple sides and/or portions. For example, the magnet holder 312 may have a first side, a second side, and a third side. The first side may be a lateral side extending along the X-axis and along the side surfaces of the optical elements. The second side may be a lateral side extending along the X-axis and along opposite side surfaces of the optical elements. The third side may be a distal/object side extending along the Y-axis, and may be positioned behind at least a portion of the reflecting surface side of the prism 304 (e.g., such that the prism 304 is disposed between the lens group 302 and the magnet holder 312).

According to some examples, a first portion of the magnet holder 312 (e.g., the first side of the magnet holder 312) may extend proximate a first side of the lens barrel 308, a second portion of the magnet holder 312 (e.g., the second side of the magnet holder 312) may extend proximate a second side of the lens barrel 308 that is opposite the first side of the lens barrel 308, and a third portion of the magnet holder 312 (e.g., the third side of the magnet holder 312) may be tucked under a portion of the prism 304 and may extend from the first portion to the second portion, e.g., as shown in FIG. 4. In some embodiments, the magnet holder 312 (and/or outer carrier structure) may have a different number of sides and/or a different combination of sides than shown in FIGS. 3 and 4.

As will be discussed below with reference to FIGS. 7A-7C, the inner carrier structure (e.g., lens barrel 308 and/or lens carrier 310) may be suspended from the outer carrier structure (e.g., magnet holder 312) via a suspension arrangement. Additionally, or alternatively, the outer structure may be suspended from a fixed (or static) structure (e.g., base structure 314). In some embodiments, the suspension arrangement may include one or more top springs 316, one or more bottom springs 318, and/or one or more suspension wires 320. The suspension arrangement may allow the inner carrier structure to move relative to the outer carrier structure. Furthermore, the suspension arrangement may allow the inner structure to move together with the outer carrier structure relative to the fixed structure. In various examples, the lens carrier 310 may be fixedly attached to the lens barrel 308, and the lens barrel 308 may be fixedly attached to the lens group 302. As such, movement of the lens carrier 310 and/or the lens barrel 308 (e.g., due to actuation of one or more actuators of the actuator module) may cause movement of the lens group 302, such that the lens group 302 moves together with the lens barrel 308 and the lens carrier 310. According to some embodiments, the fixed structure may include a component of the camera 300 to which the carrier arrangement is moveably connected (e.g., via suspension elements). The fixed structure may be fixed relative to movement of the carrier arrangement. In some examples, the fixed structure may include multiple components that are joined or otherwise fixed relative to each other.

In various embodiments, the actuator module may include one or more AF VCM actuators and/or one or more OIS VCM actuators. In some embodiments, the actuator module may include an AF VCM actuator (e.g., to provide AF movement), an OIS-Y VCM actuator (e.g., to provide OIS-Y movement), and an OIS-Z VCM actuator (e.g., to provide OIS-Z movement), each of which may include one or more magnets and one or more coils.

In some examples, the AF VCM actuator may include an AF magnet 322 (e.g., a single-pole magnet, a dual-pole magnet, etc.) and an AF coil 324. The AF magnet 322 may be attached to the base structure 314. The AF coil 324 may be attached to the magnet holder 312. In some embodiments, the AF magnet 322 may have a longest dimension that is substantially parallel to a longest dimension of the AF coil 324. In some embodiments, the AF coil 324 may be oriented such that directions of current flow through the AF coil 324 define a plane that is substantially parallel to a surface of the base structure 314 (e.g., the surface on which the AF magnet 322 is mounted) and/or substantially parallel to the X-Y plane. The AF magnet 322 and the AF coil 324 may be located proximate one another, and the AF coil 324 may be electrically driven to magnetically interact with the AF magnet 322 to produce Lorentz forces that move the AF coil 324, the magnet holder 312, and/or the lens group 302 along an axis (e.g., along the X-axis) to provide AF movement. The AF magnet 322, being attached to the base structure 314, may remain stationary relative to the movement of the AF coil 324. In various embodiments, the AF VCM actuator may be tucked within a space under a portion of the prism 304, e.g., as indicated in FIG. 4. In this manner, the impact of the AF VCM actuator on the dimension of the system along its long axis (e.g., the X-axis) and along its vertical axis (e.g., the Z-axis) may be reduced or eliminated.

In some embodiments, the OIS-Y VCM actuator and the OIS-Z VCM actuator may share one or more OIS magnets 326 (also referred to herein as “shared OIS magnets”). In some embodiments, the shared OIS magnets 326 may be dual-pole magnets. The shared OIS magnets 326 may be attached to the magnet holder 312, e.g., at opposing sides of the lens group 302.

According to some examples, the OIS-Y VCM actuator may include one or more OIS-Y coils 328. The OIS-Y coils 328 may be coupled to the base structure 314. For example, the OIS-Y coils may be on a flex circuit 330 that is attached or otherwise coupled to the base structure 314. In some embodiments, each OIS-Y coil 328 may be located below a respective shared OIS magnet 326. The OIS-Y coils 328 may be electrically driven to magnetically interact with the shared OIS magnets 326 to produce Lorentz forces that move the shared OIS magnets 326, the magnet holder 312, and/or the lens group 302 along an axis (e.g., along the Y-axis) to provide OIS-Y movement (e.g., movement that shifts an image projected on the image sensor 306 in one or more directions parallel to the Y-axis). The OIS-Y coils 328, being coupled to the base 314, may remain stationary relative to the movement of the shared OIS magnets 326. In some embodiments, each of the shared OIS magnets 326 may have respective longest dimensions that are substantially parallel to respective longest dimensions of the OIS-Y coils 328. In some embodiments, the respective longest dimensions of the shared OIS magnets 326 and the OIS-Y coils 328 may be substantially parallel to a longest dimension of the system. Furthermore, the respective longest dimensions of the shared OIS magnets 326 and the OIS-Y coils 328 may be substantially orthogonal to the respective longest dimensions of the AF magnet 322 and the AF coil 324 in some embodiments. According to various embodiments, the OIS-Y coils 328 may be oriented such that directions of current flow through the OIS-Y coils 328 define a respective plane that is substantially parallel to a surface of the base structure 314.

According to some examples, the OIS-Z VCM actuator may include one or more OIS-Z coils 332. The OIS-X coils 332 may be attached to the lens carrier 310 (and/or the lens barrel 308). In some embodiments, each OIS-Z coil 332 may be located between a respective shared OIS magnet 326 and the lens group 302. The OIS-Z coils 332 may be electrically driven to magnetically interact with the shared OIS magnets 326 to produce Lorentz forces that move the OIS-Z coils 332, the lens carrier 310 (and/or the lens barrel 308), and the lens group 302 along an axis (e.g., along the Z-axis), relative to the magnet holder 312 and/or the base structure 314, to provide OIS-Z movement (e.g., movement that shifts an image projected on the image sensor 306 in one or more directions parallel to the Z-axis). In some embodiments, each of the shared OIS magnets 326 may have respective longest dimensions that are substantially parallel to respective longest dimensions of the OIS-Z coils 332. In some embodiments, the respective longest dimensions of the shared OIS magnets 326 and the OIS-Z coils 332 may be substantially parallel to a longest dimension of the system. Furthermore, the respective longest dimensions of the shared OIS magnets 326 and the OIS-Z coils 332 may be substantially orthogonal to the respective longest dimensions of the AF magnet 322 and the AF coil 324 in some embodiments. According to various embodiments, the OIS-Z coils 332 may be oriented such that directions of current flow through the OIS-Z coils 332 define a respective plane that is substantially orthogonal to a surface of the base structure 316.

In various embodiments, the base structure 314 may include a first portion 334 and a second portion 336. The first portion 334 may be located below the prism 304 and the lens group 302. Furthermore, the first portion 334 may define a first plane that is parallel to the optical axis defined by the lens group 302. In some embodiments, the second portion 336 may define a second plane that is orthogonal to the optical axis. In some examples, the second portion 336 may extend upwards (e.g., in the Z-axis direction) from the first portion 334 to form an L-shaped base structure 314. According to some embodiments, the first portion 334 and the second portion 336 may be formed together as a single component. In other embodiments, the base structure 314 may be formed from multiple components. As a non-limiting example, the first portion 334 and the second portion 336 may be formed individually and coupled together to form the base structure 314.

According to some embodiments, the first portion 334 of the base structure 314 may define a recess 338 for receiving at least a portion of the lens carrier 310, at least a portion of the lens barrel 308, and/or at least a portion of the lens group 302. The recess 338 may enable the lens group 302 to be located lower along the Z-axis direction than it would be without the recess 338, thereby enabling a reduction in the Z-axis dimension of at least the portion of the system that includes the lens group 302.

In some embodiments, the second portion 336 of the base structure 314 may define a window 340 that allows light to pass through the second portion 336 and to the image sensor 306. For example, the image sensor 306 may be attached to a substrate 342, and the substrate may be attached to the second portion 336 such that at least a portion of the image sensor receives light that passes through the window 340.

In some embodiments, the camera 300 may include one or more enclosures that cover at least a portion of the camera 300 (e.g., internal camera components). For example, the camera 300 may include an inner can 344 and/or an outer can 346 (not shown in FIG. 4). In some examples, the inner can 344 may cover at least a portion of the actuator module. In a non-limiting example, the inner can 344 may be shaped to fit over the magnet holder 312 without covering uppermost surfaces of the prism 304 or the lens barrel 308 (and/or the lens carrier 310). The outer can 346 may cover the inner can 344 and the lens barrel 308 (and/or the lens carrier 310) without covering uppermost surfaces of the prism 304.

In some embodiments, the camera 300 may include a stiffener 348 configured to be attached, or otherwise coupled, to the image sensor 306, the substrate 342, and/or the second portion 336 of the base structure 314. The stiffener 348 may provide structural support to the substrate 342 and/or the second portion 336 of the base structure 314. In some embodiments, the stiffener 348 may include a base portion 350 and one or more tab portions 352 that extend from the base portion 350 at a non-zero angle relative to the base portion 350. For example, the tab portion(s) 352 may extend orthogonal to base portion 350. According to some examples, the stiffener 348 may be formed by folding portions of a sheet of metal (or other suitable material) to form the tab portion(s) 352. That is, the base portion 350 and the tab portion(s) 352 may be formed of a same sheet of metal in some embodiments. In other embodiments, the base portion 350 and the tab portion(s) 352 may be formed separately and attached to form the stiffener 348. As indicated in FIG. 3, the stiffener 348 may include three tab portions 352 in some embodiments. In other embodiments, however, the stiffener 348 may include fewer or more tab portion(s) 352. The stiffener may be configured to enclose a portion of the camera 300 that is proximate the image sensor 306 and that is not covered by the outer can 346 and/or the first portion 334 of the base structure 314. In various embodiments, the base portion 350 may define a plane that is orthogonal to the optical axis defined by the lens group 302 and/or that is parallel to the image sensor 306.

In some examples, the camera 300 may include a prism holder 354 that holds the prism 304. The prism holder 354 may enclose one or more sides of the prism 304. In various embodiments, the prism holder 354 may not enclose at least a portion of the object side of the prism 304, so as to allow light to enter the prism 304. The prism 304 may be attached to one or more fixed (or static) structures of the camera 300 via the prism holder 354. For example, the prism holder 354 may be attached to the outer can 346 in some cases.

In some embodiments, the camera 300 may include a filter 402 (e.g., an infrared filter) (not shown in FIG. 3). The filter 402 may be coupled to the substrate, e.g., as indicated in FIG. 4. For instance, the filter 402 may be located between the lens group 302 and the image sensor 306 such that light passes through the filter 402 before reaching the image sensor 306.

FIG. 5 illustrates a perspective view of an example base structure 500 of a camera having a folded optics arrangement. The base structure 500 may include components that are similar to, or the same as, components of the base structure 314 described above with reference to FIGS. 3 and 4.

According to various embodiments, the base structure 500 may include a first portion 502 and a second portion 504. The first portion 502 may be located below a prism and a lens group (e.g., the prism 304 and the lens group 302 in FIGS. 3 and 4). Furthermore, the first portion 504 may define a first plane that is parallel to an optical axis defined by the lens group. In some embodiments, the second portion 504 may define a second plane that is orthogonal to the optical axis. In some examples, the second portion 504 may extend upwards (e.g., in the Z-axis direction) from the first portion 502 to form an L-shaped base structure 500. According to some embodiments, the first portion 502 and the second portion 504 may be formed together as a single component. In other embodiments, the base structure 500 may be formed from multiple components. As a non-limiting example, the first portion 502 and the second portion 504 may be formed separately and coupled together to form the base structure 500.

According to some embodiments, the first portion 502 of the base structure 500 may define a recess 506 for receiving at least a portion of a lens carrier (e.g., the lens carrier 310 in FIGS. 3 and 4), at least a portion of a (e.g., the lens barrel 308 in FIGS. 3 and 4), and/or at least a portion of a (e.g., the lens group 302 in FIGS. 3 and 4). The recess 506 may enable the lens group to be located lower along the Z-axis direction than it would be without the recess 506, thereby enabling a reduction in the Z-axis dimension of at least a portion of a camera system (e.g., a portion that includes the lens group).

In some embodiments, the second portion 504 of the base structure 500 may define a window 508 that allows light to pass through the second portion 504 and to an image sensor 510. For example, the image sensor 510 may be attached to a substrate 512, and the substrate 512 may be attached to the second portion 504 such that at least a portion of the image sensor 510 receives light that passes through the window 508.

As indicated in FIG. 5, one or more components may also be coupled to the first portion 502 of the base structure 500. For example, as similarly discussed above with reference to FIGS. 3 and 4, a flex circuit 514, one or more coils 516 (e.g., OIS-Y coils), and one or more magnets 518 (e.g., an AF magnet) may be coupled to the first portion 502 of the base structure 500. In some embodiments, the flex circuit 514 and the magnet 518 may be mounted on a top surface of the first portion 502, e.g., as indicated in FIG. 5. The coil(s) 516 may be mounted on a top surface of the flex circuit 514. FIG. 5 further shows a coil 520 (e.g., an AF coil) disposed proximate the magnet 518. The coil 520 may be attached to a magnet holder (e.g., the magnet holder 312 in FIGS. 3 and 4) (not shown in FIG. 5), and may be configured to magnetically interact with magnet 518, e.g., to enable AF movement of the a lens group disposed above (and/or at least partially within) the recess 506 defined by the first portion 502 of the base structure 500.

In some embodiments, the base structure 500 may include electrical signal traces (not shown) that convey electrical signals (e.g., power and/or control signals) between the second portion 504 and the first portion 502. As a non-limiting example, the electrical signal traces may be conveyed from the image sensor 510 to the flex circuit 514 via the substrate 512, the second portion 504, and/or the first portion 502.

FIG. 6 illustrates a perspective view of an example camera 600 having a folded optics arrangement, with an outer can 602 (e.g., a shield can) covering at least a portion of the internal components of the camera 600. The camera 600 may include components that are similar to, or the same as, components of the camera 300 described above with reference to FIGS. 3 and 4. Furthermore, the outer can 602 may be similar to, or the same as, the outer can 346 described above with reference to FIG. 3.

In some embodiments, the outer can 602 may configured to partly enclose an upper portion of the camera 600. Furthermore, the outer can 600 may be configured to enclose one or more side portions of the camera 600. For example, as indicated in FIG. 6, the outer can 600 may enclose three side portions of the camera 600. The camera 600 may include a base structure 604 that encloses a bottom portion of the camera 600, and a stiffener 606 that encloses another side portion of the camera (e.g., a side portion that is not enclosed by the outer can 602 or the base structure 604.

As shown in FIG. 6, the camera 600 may include a prism 608 attached to a prism holder 610. The outer can 602 may be formed such that it does not enclose (or cover) an upper portion of the prism 608 and/or an upper portion of the prism holder 610. As such, an object side of the prism 608 may be exposed such that light is capable of entering the prism 608 via its object side.

FIGS. 7A-7C each illustrate a respective view of an example suspension arrangement 700 for a camera having a folded optics arrangement. FIG. 7A shows a perspective view of the suspension arrangement 700. FIG. 7B shows a top view of the suspension arrangement 700. FIG. 7C shows a side view of the suspension arrangement 700.

In some embodiments, the camera may include a lens group 702, e.g., between a prism and an image sensor as discussed above with reference to at least FIGS. 1, 3, and 4. The lens group 702 may include one or more lens elements disposed within a lens barrel 704. Furthermore, in various embodiments, the camera may include a lens carrier 706 configured to hold the lens barrel 704 and/or the lens group 702. For instance, the lens carrier 706 may at least partially surround the lens barrel 704 in some embodiments.

In various embodiments, the lens carrier 706 (and/or lens barrel 704) may be suspended from a magnet holder 708 via the suspension arrangement 700. Additionally, or alternatively, the magnet holder 708 may be suspended from a fixed structure (not shown) via the suspension arrangement 700. The suspension arrangement 700 may allow the lens carrier 706 to move relative to the magnet holder 708. Furthermore, the suspension arrangement 700 may allow the lens carrier 706 to move together with the magnet holder 708 relative to the fixed structure.

According to some embodiments, the suspension arrangement 700 may include a set of one or more top springs 710 attached to respective top corner portions of the magnet holder 708 and the lens carrier 706. For instance, FIGS. 9A-9B show four top springs 710, each of which includes a respective first end that is attached to a respective corner portion of the magnet holder 708, and a second end that is attached to a corresponding corner portion of the lens carrier 706 (e.g., a corner portion of the lens carrier 706 that is located proximate the respective corner portion of the magnet holder 708). Furthermore, a respective suspension wire 712 may extend downward from each of the top springs 710. A bottom end portion 714 of the respective suspension wire 710 may be attached to a fixed (or static) structure, e.g., a fixed base structure of the camera. In various embodiments, any number of the top springs 710 may be connected such that they form a single piece of material having individual portions that can independently flex. Reducing the number of individual pieces in this manner may be desirable from a manufacturing standpoint in some cases.

According to some embodiments, the suspension arrangement 700 may include a set of one or more bottom springs 716 attached to respective bottom corner portions of the magnet holder 708 and the lens carrier 706. The bottom springs 716 may include a first end that is attached to a respective corner portion of the magnet holder 708, and a second end that is attached to a corresponding corner portion of the lens carrier 706. In some embodiments, a respective suspension wire (not shown) may extend upward from each of the bottom springs 716. A top end portion of the respective suspension wire may be attached to a fixed structure of the camera.

In some embodiments one or more suspension elements used for suspending the magnet holder 708 may be decoupled from one or more suspension elements used for suspending the lens carrier 706. For example, as indicated in FIG. 7A, the top spring 710 may have a fixed portion 718 that is fixed relative to the magnet holder 708. The top spring 710 may have a first portion 720 that can flex relative to the magnet holder 708 and that is connected to the suspension wire 712 for suspending the magnet holder 708. Furthermore, the top spring 710 may have a second portion 722 that can independently flex relative to the magnet holder 708 and that is connected to the lens carrier 706 (e.g., at fixed portion 724 that is fixed relative to the lens carrier 706) for suspending the lens carrier 706. In some embodiments, the first portion 720 and the second portion 722 may be made from separate pieces of material.

In some embodiments, one or more of the top springs 710 and/or one or more of the bottom springs 716 may not be positioned at corners of the magnet holder 708 and/or the lens carrier 706. For example, one or more of the springs may be positioned along sides of the magnet holder 708 and/or the lens carrier 706. Furthermore, the top springs 710 and/or the bottom springs 716 may have more (or fewer) than four springs. In some embodiments, the top springs 710 may have the same number of springs as the bottom springs 716. In other embodiments, the top springs 710 may have a different number of springs than the bottom springs 716.

In some embodiments, one or more lens elements of the lens group 702 may define an optical axis that is substantially parallel to a plane defined by the set of top springs 710. Additionally, or alternatively, the optical axis may be substantially parallel to a plane defined by the set of bottom springs 716. Furthermore, a plane defined by the set of top springs 710 may be substantially parallel to a plane defined by the set of bottom springs 716. In some instances, the suspension wires 712 may extend in directions that are substantially orthogonal to the optical axis, a plane defined by the set of top springs 710, and/or a plane defined by the set of bottom springs 716.

In various embodiments, the suspension arrangement 700 may provide compliance and/or stiffness for controlled movement of the lens carrier 706 and/or the magnet holder 708. According to some examples, the suspension wires 712 may flex to allow controlled AF movement (e.g., along the X-axis) and/or OIS-Y movement (e.g., along the Y-axis) of the magnet holder 708 together with the lens carrier 706. In some instances, e.g., during such AF and/or OIS-Y movement, the set of top springs 710 and/or the set of bottom springs 716 may not flex (or may flex substantially less than the suspension wires 712). In various embodiments, the suspension wires 712 may provide compliance for such AF and/or OIS-Y movement in a controlled manner, and may provide sufficient stiffness to resist X-Y plane movement of the lens carrier (and the lens group 102) during OIS-Z movement. According to some examples, the set of top springs 710 and/or the set of bottom springs 716 may flex to allow controlled OIS-Z movement (e.g., in the Z-axis direction) of the lens carrier 706 relative to the magnet holder 708. In some instances, e.g., during such OIS-Z movement, the suspension wires 712 may not flex (or may flex substantially less than the set of top springs 710 and/or the set of bottom springs 716). In various embodiments, the top springs 710 and/or the bottom springs 716 may provide compliance for such OIS-Z movement in a controlled manner, and may provide sufficient stiffness to resist Z-axis movement of the lens carrier 706 (and the lens group 702) during OIS-Y and/or AF movement.

In some embodiments, the camera and/or the suspension arrangement 700 may include a damper that dampens movement of one or more of the suspension wires 712. For instance, the suspension wires 712 may be at least partially disposed within a viscoelastic material 726 (e.g., a viscoelastic gel). In some examples, the magnet holder 708 may define one or more pockets 728 within which the viscoelastic material 726 may be disposed. In some instances, the viscoelastic material 726 may be injected into a pocket 728 through a hole in a base structure (not shown) that at least partially surrounds the magnet holder 708. For example, an insertion needle (not shown) may be inserted through the hole in the base structure to access the pocket and inject the viscoelastic material 726 into the pocket 728. In some embodiments, protrusions may extend from corner portions of the magnet holder 708 to form the pockets 728. While FIG. 7A shows pockets 728 formed from the magnet holder 708, it should be understood that the viscoelastic material 726 may be disposed within pockets formed differently, e.g., via pockets formed of protrusions from a structure other than the magnet holder 708, pockets formed via a combination of the magnet holder 708 and one or more other structures, etc. The viscoelastic material 726 may be located along any portion(s) of the length of a suspension wire 712. In some embodiments, the viscoelastic material 726 may be located along a central portion of the length of a suspension wire 712.

In various embodiments, the suspension arrangement 700 may be used to carry signals (e.g., power and/or control signals) from the fixed structure of the camera to the magnet holder 708 and/or the lens carrier 706. For example, suspension wires 712 may carry the signals from the fixed structure to top springs 710. The top springs 710 may carry the signals (e.g., via first portion 720 and fixed portion 718) from the suspension wires 712 to the magnet holder 708, and the signals may be routed to one or more coils attached to the magnet holder 708. Additionally, or alternatively, the top springs 710 may carry the signals (e.g., via second portion 722 and fixed portion 724) from the suspension wires 712 to the lens carrier 706, and the signals may be routed to one or more coils attached to the lens carrier 706. Various portions of the suspension arrangement, the magnet holder 708, and/or the lens carrier 706 may be formed of electrically conductive material and/or may include electrical traces for carrying/routing the signals, e.g., from the fixed structure to the coils.

The AF position sensors 808 may be magnetic field sensors (e.g., Hall sensors, tunneling magnetoresistance (TMR) sensors, giant magnetoresistance (GMR) sensors, etc.) in various embodiments. An AF position sensor 808 may be disposed proximate a corresponding AF probe magnet 810 such that the AF position sensor 808 is capable of sensing one or more magnetic field components of the corresponding AF probe magnet 810, e.g., as the AF probe magnet 810 moves relative to the AF position sensor 808.

In some examples, the AF probe magnet 810 may be attached to a magnet holder 812. The magnet holder 812 may be configured to hold one or more magnets (e.g., shared OIS magnets 814). Furthermore, the magnet holder 812 may be configured to hold one or more coils (e.g., AF coil 816).

That is, some or all of the position sensors of the position sensor arrangement 800 may be attached to the flex circuit 818. Additionally, or alternatively, the flex circuit 818 may include one or more coils (e.g., OIS-Y coils 820).

In various embodiments, the AF movement position sensor arrangement 802 may include two AF position sensors 808 and two corresponding AF probe magnets 810. A first AF position sensor 808 and a first corresponding AF probe magnet 810 may form a first pair. A second AF position sensor 808 and a second corresponding AF probe magnet 810 may form a second pair that is opposite the first pair with respect to the system X-axis, e.g., as indicated in FIG. 8A. By having two such pairs, rotation about the system Z-axis due to system X-axis displacement may be cancelled out in some embodiments.

In some cases, the OIS-Y position sensor 822 may be attached to a fixed (or static) structure of the camera. For instance, the fixed structure may be the flex circuit 818 that is common to (or shared by) some or all of the position sensors of the position sensor arrangement 800. In some embodiments, the OIS-Y position sensor 822 may be attached to the flex circuit 818 below the shared OIS magnet 814 and/or below the OIS-Y coil 820, e.g., as indicated in FIGS. 8C-8D.

In various embodiments, the OIS-Y movement position sensor arrangement 804 may include two OIS-Y position sensors 822 and two corresponding shared OIS magnets 814.

In some embodiments, the OIS-Z movement position sensor arrangement 806 may include one or more OIS-Z position sensors 824 and one or more corresponding OIS-Z probe magnets 826. The OIS-Z position sensors 824 may be magnetic field sensors (e.g., Hall sensors, TMR sensors, GMR sensors, etc.) in various embodiments. An OIS-Z position sensor 824 may be disposed proximate a corresponding OIS-Z probe magnet 826 such that the OIS-Z position sensor 824 is capable of sensing one or more magnetic field components of the corresponding OIS-Z probe magnet 826, e.g., as the OIS-Z probe magnet 826 moves relative to the OIS-Z position sensor 824.

In some examples, the OIS-Z probe magnet 826 may be attached to a lens carrier 828 (or a lens barrel). The lens carrier 828 may be configured to hold a lens barrel 830 and/or a lens group 832 (e.g., a lens group having one or more lens elements disposed within the lens barrel 830). Furthermore, the lens carrier 828 may be configured to hold one or more coils (e.g., OIS-Z coils 834). In some embodiments, the OIS-Z position sensor 824 may be attached to a fixed (or static) structure of the camera.

By having two such pairs, rotation about the system Z-axis (due to system Z-axis displacement) and/or external field effects may be cancelled out in some embodiments.

In some embodiments, the flex circuit 818 may be coupled to (e.g., in electrical contact with) an image sensor package (not shown). Additionally, or alternatively, the image sensor package may be coupled to (e.g., in electrical contact with) another flex circuit.

In some embodiments, the AF movement position sensor arrangement 902 may include one or more AF position sensors 908 and one or more corresponding AF probe magnets 910, e.g., as shown in FIGS. 9A and 9B. The AF position sensors 908 may be magnetic field sensors (e.g., Hall sensors, tunneling magnetoresistance (TMR) sensors, giant magnetoresistance (GMR) sensors, etc.) in various embodiments. An AF position sensor 908 may be disposed proximate a corresponding AF probe magnet 910 such that the AF position sensor 908 is capable of sensing one or more magnetic field components of the corresponding AF probe magnet 910, e.g., as the AF probe magnet 910 moves (e.g., along the Z-axis) relative to the AF position sensor 908.

In some examples, the AF probe magnet 910 may be attached to a magnet holder 912. The magnet holder 912 may be configured to hold one or more magnets (e.g., shared OIS magnets 914 shown in FIGS. 9A and 9C). Furthermore, the magnet holder 912 may be configured to hold one or more coils, such as an AF coil (not shown). In some embodiments, the AF position sensor 908 may be attached to a fixed (or static) structure of the camera. For instance, the fixed structure may be a flex circuit 916 that is common to (or shared by) some or all of the position sensors of the position sensor arrangement 900. That is, some or all of the position sensors of the position sensor arrangement 900 may be attached to the flex circuit 916. Additionally, or alternatively, the flex circuit 916 may include one or more coils (e.g., OIS-Y coils 918).

In some embodiments, due to the magnitude of the magnetic field produced by the shared OIS magnet 914, the OIS-Y movement position sensor arrangement 904 may not require a separate probe magnet and/or more than one OIS-Y movement position sensors.

In some cases, the OIS-Y position sensor 922 may be attached to a fixed (or static) structure of the camera.

Audio circuitry 1010, speaker 1011, and microphone 1013 provide an audio interface between a user and device 1000. Audio circuitry 1010 receives audio data from peripherals interface 1018, converts the audio data to an electrical signal, and transmits the electrical signal to speaker 1011. Speaker 1011 converts the electrical signal to human-audible sound waves. Audio circuitry 1010 also receives electrical signals converted by microphone 1013 from sound waves. Audio circuitry 1010 converts the electrical signal to audio data and transmits the audio data to peripherals interface 1018 for processing. Audio data may be retrieved from and/or transmitted to memory 1002 and/or RF circuitry 1008 by peripherals interface 1018. In some embodiments, audio circuitry 1010 also includes a headset jack (e.g., 1112, FIG. 11). The headset jack provides an interface between audio circuitry 1010 and removable audio input/output peripherals, such as output-only headphones or a headset with both output (e.g., a headphone for one or both ears) and input (e.g., a microphone).

I/O subsystem 1006 couples input/output peripherals on device 1000, such as touch screen 1012 and other input control devices 1016, to peripherals interface 1018. I/O subsystem 1006 may include display controller 1056 and one or more input controllers 1060 for other input or control devices. The one or more input controllers 1060 receive/send electrical signals from/to other input or control devices 1016. The other input control devices 1016 may include physical buttons (e.g., push buttons, rocker buttons, etc.), dials, slider switches, joysticks, click wheels, and so forth. In some alternate embodiments, input controller(s) 1060 may be coupled to any (or none) of the following: a keyboard, infrared port, USB port, and a pointer device such as a mouse.

The one or more buttons may include a push button (e.g., 1106, FIG. 11).

Touch-sensitive display 1012 provides an input interface and an output interface between the device and a user. Display controller 1056 receives and/or sends electrical signals from/to touch screen 1012. Touch screen 1012 displays visual output to the user. The visual output may include graphics, text, icons, video, and any combination thereof (collectively termed “graphics”). In some embodiments, some or all of the visual output may correspond to user-interface objects.

Touch screen 1012 has a touch-sensitive surface, sensor or set of sensors that accepts input from the user based on haptic and/or tactile contact. Touch screen 1012 and display controller 1056 (along with any associated modules and/or sets of instructions in memory 1002) detect contact (and any movement or breaking of the contact) on touch screen 1012 and converts the detected contact into interaction with user-interface objects (e.g., one or more soft keys, icons, web pages or images) that are displayed on touch screen 1012. In an example embodiment, a point of contact between touch screen 1012 and the user corresponds to a finger of the user.

Touch screen 1012 may use LCD (liquid crystal display) technology, LPD (light emitting polymer display) technology, or LED (light emitting diode) technology, although other display technologies may be used in other embodiments. Touch screen 1012 and display controller 1056 may detect contact and any movement or breaking thereof using any of a variety of touch sensing technologies now known or later developed, including but not limited to capacitive, resistive, infrared, and surface acoustic wave technologies, as well as other proximity sensor arrays or other elements for determining one or more points of contact with touch screen 1012. In an example embodiment, projected mutual capacitance sensing technology is used, such as that found in the iPhone®, iPod Touch®, and iPad® from Apple Inc. of Cupertino, Calif.

Touch screen 1012 may have a video resolution in excess of 800 dpi. In some embodiments, the touch screen has a video resolution of approximately 860 dpi. The user may make contact with touch screen 1012 using any suitable object or appendage, such as a stylus, a finger, and so forth. In some embodiments, the user interface is designed to work primarily with finger-based contacts and gestures, which can be less precise than stylus-based input due to the larger area of contact of a finger on the touch screen. In some embodiments, the device translates the rough finger-based input into a precise pointer/cursor position or command for performing the actions desired by the user.

In some embodiments, in addition to the touch screen, device 1000 may include a touchpad (not shown) for activating or deactivating particular functions. In some embodiments, the touchpad is a touch-sensitive area of the device that, unlike the touch screen, does not display visual output. The touchpad may be a touch-sensitive surface that is separate from touch screen 1012 or an extension of the touch-sensitive surface formed by the touch screen.

Device 1000 also includes power system 1062 for powering the various components. Power system 1062 may include a power management system, one or more power sources (e.g., battery, alternating current (AC)), a recharging system, a power failure detection circuit, a power converter or inverter, a power status indicator (e.g., a light-emitting diode (LED)) and any other components associated with the generation, management and distribution of power in portable devices.

Device 1000 may also include one or more optical sensors or cameras 1064. FIG. 10 shows an optical sensor 1064 coupled to optical sensor controller 1058 in I/O subsystem 1006. Optical sensor 1064 may include charge-coupled device (CCD) or complementary metal-oxide semiconductor (CMOS) phototransistors. Optical sensor 1064 receives light from the environment, projected through one or more lens, and converts the light to data representing an image. In conjunction with imaging module 1043 (also called a camera module), optical sensor 1064 may capture still images or video. In some embodiments, an optical sensor 1064 is located on the back of device 1000, opposite touch screen display 1012 on the front of the device, so that the touch screen display 1012 may be used as a viewfinder for still and/or video image acquisition. In some embodiments, another optical sensor is located on the front of the device so that the user's image may be obtained for videoconferencing while the user views the other video conference participants on the touch screen display.

Device 1000 may also include one or more proximity sensors 1066. FIG. 10 shows proximity sensor 1066 coupled to peripherals interface 1018. Alternately, proximity sensor 1066 may be coupled to input controller 1060 in I/O subsystem 1006. In some embodiments, the proximity sensor 1066 turns off and disables touch screen 1012 when the multifunction device 1000 is placed near the user's ear (e.g., when the user is making a phone call).

Device 1000 includes one or more orientation sensors 1068. In some embodiments, the one or more orientation sensors 1068 include one or more accelerometers (e.g., one or more linear accelerometers and/or one or more rotational accelerometers). In some embodiments, the one or more orientation sensors 1068 include one or more gyroscopes. In some embodiments, the one or more orientation sensors 1068 include one or more magnetometers. In some embodiments, the one or more orientation sensors 1068 include one or more of global positioning system (GPS), Global Navigation Satellite System (GLONASS), and/or other global navigation system receivers. The GPS, GLONASS, and/or other global navigation system receivers may be used for obtaining information concerning the location and orientation (e.g., portrait or landscape) of device 1000. In some embodiments, the one or more orientation sensors 1068 include any combination of orientation/rotation sensors. FIG. 10 shows the one or more orientation sensors 1068 coupled to peripherals interface 1018. Alternately, the one or more orientation sensors 1068 may be coupled to an input controller 1060 in I/O subsystem 1006. In some embodiments, information is displayed on the touch screen display 1012 in a portrait view or a landscape view based on an analysis of data received from the one or more orientation sensors 1068.

In some embodiments, the software components stored in memory 1002 include operating system 1026, communication module (or set of instructions) 1028, contact/motion module (or set of instructions) 1030, graphics module (or set of instructions) 1032, text input module (or set of instructions) 1034, Global Positioning System (GPS) module (or set of instructions) 1035, arbiter module 1058 and applications (or sets of instructions) 1036. Furthermore, in some embodiments memory 1002 stores device/global internal state 1057. Device/global internal state 1057 includes one or more of: active application state, indicating which applications, if any, are currently active; display state, indicating what applications, views or other information occupy various regions of touch screen display 1012; sensor state, including information obtained from the device's various sensors and input control devices 1016; and location information concerning the device's location and/or attitude.

Operating system 1026 (e.g., Darwin, RTXC, LINUX, UNIX, OS X, WINDOWS, or an embedded operating system such as VxWorks) includes various software components and/or drivers for controlling and managing general system tasks (e.g., memory management, storage device control, power management, etc.) and facilitates communication between various hardware and software components.

Communication module 1028 facilitates communication with other devices over one or more external ports 1024 and also includes various software components for handling data received by RF circuitry 1008 and/or external port 1024. External port 1024 (e.g., Universal Serial Bus (USB), FIREWIRE, etc.) is adapted for coupling directly to other devices or indirectly over a network (e.g., the Internet, wireless LAN, etc.). In some embodiments, the external port is a multi-pin (e.g., 30-pin) connector.

Contact/motion module 1030 may detect contact with touch screen 1012 (in conjunction with display controller 1056) and other touch sensitive devices (e.g., a touchpad or physical click wheel). Contact/motion module 1030 includes various software components for performing various operations related to detection of contact, such as determining if contact has occurred (e.g., detecting a finger-down event), determining if there is movement of the contact and tracking the movement across the touch-sensitive surface (e.g., detecting one or more finger-dragging events), and determining if the contact has ceased (e.g., detecting a finger-up event or a break in contact). Contact/motion module 1030 receives contact data from the touch-sensitive surface. Determining movement of the point of contact, which is represented by a series of contact data, may include determining speed (magnitude), velocity (magnitude and direction), and/or an acceleration (a change in magnitude and/or direction) of the point of contact. These operations may be applied to single contacts (e.g., one finger contacts) or to multiple simultaneous contacts (e.g., “multitouch”/multiple finger contacts). In some embodiments, contact/motion module 1030 and display controller 1056 detect contact on a touchpad.

Contact/motion module 1030 may detect a gesture input by a user. Different gestures on the touch-sensitive surface have different contact patterns. Thus, a gesture may be detected by detecting a particular contact pattern. For example, detecting a finger tap gesture includes detecting a finger-down event followed by detecting a finger-up (lift off) event at the same position (or substantially the same position) as the finger-down event (e.g., at the position of an icon). As another example, detecting a finger swipe gesture on the touch-sensitive surface includes detecting a finger-down event followed by detecting one or more finger-dragging events, and subsequently followed by detecting a finger-up (lift off) event.

Graphics module 1032 includes various known software components for rendering and displaying graphics on touch screen 1012 or other display, including components for changing the intensity of graphics that are displayed. As used herein, the term “graphics” includes any object that can be displayed to a user, including without limitation text, web pages, icons (such as user-interface objects including soft keys), digital images, videos, animations and the like.

In some embodiments, graphics module 1032 stores data representing graphics to be used. Each graphic may be assigned a corresponding code. Graphics module 1032 receives, from applications etc., one or more codes specifying graphics to be displayed along with, if necessary, coordinate data and other graphic property data, and then generates screen image data to output to display controller 1056.

Text input module 1034, which may be a component of graphics module 1032, provides soft keyboards for entering text in various applications (e.g., contacts 1037, e-mail 1040, IM 1041, browser 1047, and any other application that needs text input).

GPS module 1035 determines the location of the device and provides this information for use in various applications (e.g., to telephone 1038 for use in location-based dialing, to camera 1043 as picture/video metadata, and to applications that provide location-based services such as weather widgets, local yellow page widgets, and map/navigation widgets).
